Question 1023068: use the 4 step method and 2 variables
If 10 pens and 15 pads of paper cost $26, and 5 pens and 10 pads cost $16, find the cost of a pen and a pad.
x=pen y=pad
10x + 15y =$26

-10x+-20y=-32
10x+15y=26
-10x+-20y=-32
-5y=-6
-5y=-5
y=6/5
5x+10(6/5)=16 5goes into 10 2times
5x+2*6=16

Question 1023226: Leap years occur every four years, but sometimes a leap year is skipped. This is to offset the difference between the observed number of days and the tropical year, calculated in the previous problem, which will continue to increase over time, and to keep the calendar in sync with the seasons. The rule for whether a year is a leap year or not is that every year which is perfectly divisible by four is a leap year except for years that are divisible by 100 but not 400. How many years between now and the year 3000 inclusive will be skipped leap years?
